Strange. I downloaded only the "Download Music Restoration Mod 1.2.2 (906 MB)" first and it created no changes in the game before using the patch. I’ll try again
Edit: It works but I can only listen to the original music. When I switch to the new music in the preferences, no music plays.
The original music in the preferences screen is the recommended setting. When switching in-game, the music will only start playing at the start of a new scene. That's because of how the game is coded and run in the Ren'Py engine. I'd say the mod is likely correctly installed now. Enjoy!
Speaking of the music restoration mod, how good is it? I thought the music in the base game was already pretty darn good.
I mostly agree with Elhemeer above, but would strongly recommend the Music Restoration Mod to new players. You'd be missing out on many good, sometimes great songs, that really add a lot to the experience. If I'm correct, Drifty replaced the original songs that were censored with licensed songs that already played in other scenes and the final chapter. So nothing is really lost when using the mod, there is just more variety and some of the original music fits better to the scenes, in my opinion.
Like Elhemeer stated, some players might prefer the Multi Mod. I haven't tried that one, so I can't comment on it. But overall, I think players are better off using one of these mods and experience the original music, as it was intended by the developer.
